IMPROVEMENT IN STOP-COCKS.

Specification forming part cf Letters Patent No. 144,700, dated November 18, 1875 application led March 7, 1873.

To all 'whom it may concern:

Be it known that we, LOUIS G. RODIER and FRANCIS G. BATns, of Springfield, inthe county of Hampden and State of Massachusetts, have invented a new Improvement in Water-Cocks; and we do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and

exact description of the same, and which said drawings constitute part of this specication, and represent, in-

Figure l, a perspective view 5 and in Fig. 2,

' a vertical central section.

This invention relates to an improvement in cocks or gates designed for water-pipes and for like purposes, the object being to impart to the gate a rotary movement transversely across the opening for the flow 5 and the invention consists in the arrangement of a gate let according to the purpose desired.

A is the case, of any required form, constructed with an inlet, B, and outlet C. Within this case the valve-chamber D is formed, and Upon the form of a gear, is made or attached, as seen in Fig. 2; and upon one side of the chamber a rack, F, is formed, the teeth of whichvcorrespond to the teeth on the valve, so that as the valve is raised vertically, or in a line parallel with the rack, the teeth of the valve in such movement, meshing into the teeth of the rack, will cause the valve to rotate as it moves, the

axis of rotation being substantially parallel with the water-way. i The valve is best operated by an endles screw, H, arranged to extend through the case, and provided with suitable means G for turning. The threads of the screw work in the teeth on the valve, so that, as the screw is turned in one direction, it will move the valve from the opening, as up tothe position denoted in broken lines, Fig. 2, and, in the other direction, will return or close the valve, the

.valve rotating, as before described, transl versely across the water-way, or the axis of rotation being substantially parallel with the water-way.

While we believe this to be the best method would be liable to work its way into the pipes. i

Another great advantage of this construction is the leverage which is aifordedin the movement of the valve to work it against the pressure which is naturally brought upon it.

We claim as our invention- The valve E, arranged in a chamber transversely to the waterway, constructed and combined with a rack, F, and means for imparting a transverse movement to the valve, so that,

in the movement of the valve, a combined transverse and rotary movement is imparted thereto, substantially as set forth.
